10. Summary of simulation results

The vertical and horizontal wave length are about 10 km and 12-16 km.
The horizontal scale is similar to that of convection cell.

The vertical phase velocity are about 10 m/sec.
The vertical group velocity estimated by using dispersion relation is about several m/sec.
The traveling time from the surface to 50 km hight is 1 or 2 hours.

The distribution of turbulent diffusion coefficient suggests existence of wave breaking and mixing.
